Check Out MORE Smokin' Post-Baby Bodies!

Looks like there was some real drama going on ahead of Dream Kardashian's birth.

In a new preview for the upcoming "Rob & Chyna Baby Special," we get an inside look at the famous duo as they take Lamaze classes, celebrate King Cairo's birthday party, have one crazy baby shower featuring belly dancers and, finally, welcome their newborn baby girl into the world.

There's also some major beef going on between Kris Jenner and Chyna's mom, Tokyo Toni.

Check out this intense sneak peek:

When Chyna is wheeled into the delivery room, things turn emotional. "I'm freaking out," Chyna weeps, wiping tears from her eyes.

The episode airs Sunday, December 18th on E! -- and you know you'll be watching, right? We sure will be!

And speaking of all things post-baby, can we talk about how amazing the hot mama looks just days after giving birth? The photo up top was taken over the weekend, after Chyna revealed she's already lost 15 pounds since giving birth.

After sharing a pic of her flat tummy on Instagram on Sunday, she also clapped back at fans who accused her of having "surgery" to drop the weight so fast.

"So I posted a picture of my belly yesterday and the only reason it got that flat, you guys, is from breastfeeding and breast pumping and from my body already being small before my pregnancy," said in a Snapchat video. "Not surgery guys," she added.

Chyna looks positively amazing with that flat tummy and off-the-chain hair, right?
